10 Best Ultrasonic Pest Repeller Birds 2025 in the United States

The Bird-X Critter Blaster PRO is designed to keep a wide variety of birds and animals away using ultrasonic and sonic sounds rather than harmful chemicals or traps. It covers a large area of up to 6 acres, making it suitable for big outdoor spaces like vineyards, orchards, or landfills. The device emits sounds in the 2–10 kHz frequency range through four speakers, producing loud noise levels around 105–110 dB, which helps irritate and discourage critters from entering the area. It comes with a weatherproof control box and can be powered via AC adapter or batteries, allowing flexible installation in many environments. The system includes eight different animal distress sounds that play at intervals to prevent animals from getting used to one sound. This variety enhances its effectiveness compared to basic ultrasonic repellers that often use a single tone.

The device is relatively heavy at 9 pounds and somewhat large, which may make moving it around less convenient. Also, while it is weather-resistant, it might require some care during extreme weather conditions. If you need a humane, chemical-free way to protect large outdoor spaces from birds and other critters, this product offers strong coverage and multiple sound options, though it might be more than necessary for smaller areas or casual use.

The Ultrason X by Bird-X is an outdoor ultrasonic bird repeller designed to keep a variety of nuisance birds away, including pigeons, sparrows, and crows. It uses a control box connected to four speakers, each with 100 feet of wire, allowing it to cover up to 3,600 square feet in total, making it suitable for medium-sized yards or gardens where birds are a problem.

This device operates silently for humans by emitting ultrasonic sound frequencies that are inaudible to people but bothersome to birds. It can be programmed to work day and night, providing continuous protection. The unit requires alkaline A batteries to operate, so regular battery replacement is necessary, which may be less convenient compared to models with plug-in power sources or rechargeable options.

The product does not specify its level of weather resistance, so it is advisable to take extra precautions to protect it from rain or extreme weather conditions if you live in such areas. This bird repeller is a good choice for homeowners seeking to manage bird issues outdoors across a reasonably large area without noise disturbance, while also considering battery maintenance and protective measures against weather.

The Broox 2025 Upgraded Solar Animal Repellent is designed to keep a wide variety of outdoor animals away from your garden or yard without using chemicals. It uses ultrasonic sound frequencies between 13.5kHz and 45.5kHz, combined with flashing LED lights triggered by a motion detector. This helps repel animals like cats, squirrels, deer, rabbits, and raccoons in a humane way by creating an uncomfortable environment for them. The device covers a detection angle of 110° and detects movement up to 20–25 feet, offering decent protection for small to medium-sized outdoor areas.

One of its strong points is the solar panel on top, which charges the device using sunlight, although it also supports USB charging if needed. This makes it energy-efficient and environmentally friendly. It is rated IP65 for waterproofing, meaning it can withstand rain and snow, making it suitable for year-round outdoor use. Installation is straightforward—you can stake it into the ground or mount it on a wall, and it offers five different frequency modes to target various animals effectively.

The detection range might be limited for larger areas, and ultrasonic devices depend on animals being sensitive to the sound, so results may vary. Also, it requires 3 AA batteries (included) to operate alongside solar power, which means you may need to replace them eventually. This repeller serves as a solid choice for gardeners or homeowners seeking a no-chemical, easy-to-use, and weatherproof solution to keep common nuisance animals away.
